摘要

本研究首先建立南部地區地表水與地下水之聯合運用模擬模式，然後在民國100年各需水地區之需水量與供水系統已知下，根據不同水文狀況與地下水抽取量限制，採用不同水資源調配策略進行配水模擬，並比較其差異。模擬結果之主要結論有兩點：（1）在地下水抽取量之上限為84年實際抽取量的情境下，不論水文狀況為何，決策者若根據用水效益進行調配，灌溉用水會缺水；決策者若根據水利法用水優先順序進行調配，工業用水會缺水；決策者若根據水權優先順序進行調配，養殖用水會缺水。（2）在地下水抽取量之上限為年補注量的情境下，不論水文狀況為何，在三種調配策略之下，各標的用水都會缺水。

This paper established a simulation model to integrate surface water and groundwater resources allocation of southern Taiwan. Based on forecasted future demand and supply system of water resources on the year 2011, three strategies to allocate water resources were tested under different hydrological conditions and constraints on groundwater pumpage. Two major conclusions were made according to simulation results: (1) If groundwater pumpage is constrainted on current level, for the strategy of maximizing benefits of water use, irrigation demands will have shortage and for the priorities of water use purposes, industrial water demands will be not satisfied. Besides, for the strategy based on the priority of water rights, aquaculture water supplies can not be satisfied. (2) If groundwater pumpage is constrainted on yearly quantity of recharge, considering above three strategies to allocate water resources, all demands of water use purposes will have shortage.
